Wondering if anyone knows if a 325/30R19 (Michelin PSS) will fit in the rear, even if locating the rear (PHB or Watts) is needed.
Instead of having to pick something that fits the rim, or something in a popular size for track tires, I wanted to see what tire offered improvements where I want it but still fit the overall diameter as the factory 285/35/19. Thanks to DiscountTires' calculator, I found the Michelin PSS 325/30/19 to be wider but very close elsewhere:
Section Width: + 1.58" (wider)
Sidewall: - .09" (shorter)
Overall Diam.: - .17" (smaller)
Circumf.: - .36" (smaller)
Revs/Mile: - 3.18
Speedometer reads 65MHP, Actual Speed Will Be 64.57MPH
This is for aggressive street use on a a daily driver; I'd like to make the most of the Boss's power in 2nd & 3rd gear. I'm careful when it's wet or cold, as required by the factory Pirellis, and use the wife's vehicle in the worst of it. I'm in West Texas, so it gets plenty cold but I can make do with summer-only tires without too much concern (but with due care). Replaced yearly.
So 19" because it fits the car for the street, IMO. I'll go wider in the front to help retain the balance of the car, as I have no complaints on the street. That said, I'm looking to gain traction and not degrade the aggressive street driving experience.
If it fits, I'll pick/order my rim according to what the manufacturer suggests for the tire. I know this leaves me with few choices (Nitto Invo is half the price) but the PSS in 325/30/19 looks like what I'd want if it did fit, so I don't mind buying them if I can make them work. I've been buying the factory Pirellis as it is. :
Any help or suggestions appreciated! Would rather gain traction with more rubber than look at putting the 3.55 rear in the Boss.
